All, I would like to take this opportunity to point folks to the OMG Healthcare Domain Task Force Resource Access Decision (RAD) specification as a formal computational model that can and is being used in large health care enterprises. The demanding part of the enterprise is the cumulative agreement on identifying what policies are necessary within the environment.
The RAD standard provides several mechanisms for creating polices such as attributes, timed rules, etc. It also provides the ability to assign users and associate policies with users as well as with (computational) operations. You may find the full specification here: http://www.omg.org/cgi-bin/doc?formal/2001-04-01 What would be nice to see happen in the Healthcare standards is to define standard policies such as: 1) "Review Sensitive Patient Information" 2) "Order Sensitive Laboratory Tests" etc This would ease interoperability between facilities where clinicians must access information from a variety of systems in order to make diagnosis etc. Tom _______________________________________________________ <http://www.2ab.com/>2AB, Inc. 1700 Highway 31 Calera, Alabama 35040 205-621-7455 ext 107 _____________________<http://www.2ab.com/ilock_ss.htm>iLock & <http://www.2ab.com/orb2.htm>orb2________________________ "Trusted Solutions for Distributed Business" Confidentiality Notice: This Email message and its attachments are for the sole use of the intended recipients.
